[PATCH pve-network 05/12] sdn: subnets: add dhcp-lease-time property

[Hannes Laimer <h.laimer@proxmox.com>]

Lease time is the convergence knob for mapping edits: a client picks
up a changed record at the latest one lease after the edit. Make it
configurable per subnet for dhcp backends that honor it.
